I have a Generac 2700 psi 2.5gpm model 1043-2. I have put seals in this pump numerous times and it is quite expensive. I would like to just replace the pump but can't seem to find one this style.
It has a tapered crankshaft with a keyway (keyway not used). There is a steel hex tapered sleeve that tightens down the swash plate. The bolt face to attach to the engine block is square with 2 9/16" bolt spacing on each edge (not the diagonal measure).
